Top 10 Reasons Why There Aren't Any Humans on Mars?
Friends, it must have occurred to you several times that we humans have been more than 50 years after standing on the moon, and in these 50 years, we humans have achieved significant progress.
Our technology has advanced significantly, and we now know far more than ever before about astronomy, cosmology, astrophysics, and aerospace engineering; why have we not yet stepped foot on Mars? What is the explanation behind this? What are the hurdles keeping humanity from reaching Mars? We've broken them down into ten explanations so you can grasp them simply.
First and foremost, let me clarify something. The Human Moon Mission and the Human Mars Mission are quite distinct missions. Our moon is a natural satellite that is influenced by Earth's gravitational pull, but Mars is a completely distinct planet from Earth that is thousands of times further away than the moon.
As a result, there can be no comparison between these two expeditions from Earth. So, what are the top ten reasons why there is still no human life on Mars that prevents us from getting there?
Mars is 365.82 million kilometers away from Earth. It is because Earth and Mars revolve at different rates in their separate orbits, causing them to move back and forth. As a result, the Mars mission has a launch window every 26 months when Mars and Earth are relatively close to one other.
Because we need to preserve fuel, all Mars missions have been carried out during this launch window; otherwise, the trip would be exceedingly expensive and take much longer than today's technology rockets. According to the launch window, it takes 6 months to send a spacecraft to Mars, and 6 months to return equals a one-year journey, but the story does not end there.
You can't go to Mars and return right away. You must wait until the next launch window opens. Only when Mars and Earth are in close proximity again can the 6-month trip of return begin, after which people will take 3 to 4 years to reach Mars
Astronauts will have to live in the same cramped capsule for four years, eat and sleep, and forego washing because of the difficulty of transporting water. Staying in such a tight capsule for four years will wreak havoc on his physical and mental health. It's like being locked up for four years.
Rocket Science and Technology
Our rocket technology is a major impediment. We are still using rocket technology that was developed 50 years ago today. Today's rockets are larger and more advanced than their forefathers, yet there has been no significant advancement in rocket technology in the previous 50 years.
The capsule in which humans travel to space is tiny, at the top of the rocket, similar to a totally reusable rocket, a very fuel-efficient rocket engine, or a solar-powered rocket. Only fuel is poured into the rest of the rocket since the rocket's whole fuel burns only after it escapes Earth's gravity.
The upper half of the rocket then enters space, while the rest of the rocket burns down and falls to Earth, never to be utilized again. That is why launching rockets into orbit is so costly. So, in order to return to space, we must build a new rocket.
When we compare rockets to airplanes, we can see that flying in an airplane is less expensive since we don't have to build a new plane every time. However, we need a rocket that can go to space, leaving humans behind, and then return and replace its fuel.
A rocket, like an airplane, maybe equipped to return to space; this is referred to as a completely reusable rocket. Although various partially reusable rockets, such as SpaceX's Falcon 9 and Falcon Heavy, have been developed recently, no totally reusable rocket has been developed.
Scientists and aerospace engineers are working on such rockets; SpaceX is developing a completely reusable rocket of this sort. These rockets might be ready in a few years.
How to Get Back to Earth
All of the Mars missions and excursions planned are one-way; that is, the technology to return individuals who travel from Earth to Mars has not yet been developed. NASA has been working on such rockets since the beginning, but building them is difficult.
The rocket carrying the passengers back will weigh around 18 to 20 tons, and approximately 33 to 35 tons of fuel will also be delivered. After getting so massive, it is nearly hard to land the rocket in the correct location on Mars; maybe, as a result of being so large and heavy, it explodes as soon as it hits Mars' atmosphere, killing all of the passengers together till now.
The Perseverance rover, which was just launched, is the heaviest thing ever to land, weighing 1,025 kg. Efforts are being undertaken to reduce the weight of retractable rockets. On this rocket, there may not even be a seat to sit in, yet astronauts cannot travel standing today.
Astronauts will be launched from Mars to a space station that will always rotate over Mars, and from there, they will be transported to Earth by a second rocket.
Food
Many academics across the globe believe that even if a human reaches Mars, he can be killed by hunger. As a result, the goal is to deploy 30 to 40 persons by 2030. NASA is planning this mission. If food cannot be supplied for life to feed so many people, plants will be cultivated in the Greenhouse Chamber wherever human settlements are established on Mars.
However, there is a drawback to producing plants, and that is oxygen. While oxygen is vital for human living, ingesting huge amounts of it has a direct effect on the central nervous system, lungs, and eyes. Cells begin to deteriorate, and death can occur almost instantaneously.
Scientists are working on developing such Greenhouse Chambers, in which everything is under control and there is an atmosphere similar to that of Earth.
Damage to the Human Body
Traveling in space for an extended period of time has a significant drawback. It causes the bones to deteriorate. As you spend more time in space, your bones become more fragile. In space, there is no gravitational force, and bones cannot function as they do on Earth.
This issue can be avoided by engaging in strenuous activity. However, space is inhospitable to people, and it is claimed that the human heart, which is the human heart, changes shape in space and becomes a square shape. This occurs because blood circulation in the organism is constrained by space.
In such a condition, the chances of developing heart disease are significant, and the eyes may also grow weak. It becomes less apparent, and the sun's light is still present. Astronauts are exposed to greater radiation in space than they are on Earth. It is extremely harmful to the human body.
Surgical procedure
In the same way that people are being prepared to live in space, it is also vital to have the ability to do surgery in some fashion, because a person living in space can die due to infection from a little scrape. Simple procedures including injections, teeth extractions, and bandages can be performed in orbit aboard the International Space Station.
If another difficulty arises, the astronaut is returned to Earth. This space station does not have good medical facilities, only first aid. If a person lives in space, he will become unwell, and surgery would be difficult because, owing to the lack of gravity, blood will leak from the body and fly around the cabin, contaminating everything.
In addition, anesthesia injection does not operate on individuals in space. There is no clear explanation for why this occurs. However, this implies that any operation would have to be performed without sedation, which will be extremely difficult and unpleasant.
Successful Mars Landing
To date, the majority of human-sent vehicles that have attempted to land on Mars have failed. Landing on Mars is difficult because the atmosphere of Mars is 100 times thinner than that of Earth, and as a result, the speed of the vehicle's descent does not decrease as it descends from the sky.
To lower the speed of the vehicles utilized in the human mission, large and powerful parachutes will be required, which are not currently available. Such parachutes are currently being tested. Their work is still in the early stages.
The Dust Storm (Mars)
NASA's Mars rover Opportunity landed on Mars in January 2004 to finish its 90-day mission to discover water. He completed this assignment ahead of schedule, and subsequently, he assisted NASA in accomplishing additional missions over the next 15 years. However, he lost touch with NASA in June 2018 owing to a dust storm.
On Mars, there are two kinds of storms. To begin, ordinary storms that come every few months at the beginning but are as massive as a continent are luckily moderate and only last a few weeks. The second kind of storm is the one that wiped off the Mars rover Opportunity.
The entire planet Mars is engulfed by this storm. According to Earth, a catastrophic storm happens on Mars every five and a half years, causing turmoil for months. It will cover any human objects on Mars since solar panels will be the primary source of electricity on Mars, hence solar panels will be covered by dust.
Even so, there will be so much dust in the atmosphere that sunlight will not reach the bottom for several months, putting any colony or station that has established itself there in jeopardy.
Belt of Asteroid
Assume that humanity has established on Mars, yet there is still the threat of meteorites. Our solar system's asteroid belt is located between Mars and Jupiter, which means it is near to Mars, where there are 1.9 million asteroids larger than one kilometer in diameter, and humans cannot count tiny asteroids on Mars.
The settlement would fall from space, and because Mars has no substantial atmosphere, even a little meteorite that would normally burn up in Earth's atmosphere would vanish without burning. As a result, the human settlement on Mars will be destroyed.
So far, humans lack the technology to accurately predict where meteorites would fall, and even if they are spotted, they cannot prevent them from impacting the globe.
However, scientists have developed a number of ideas that will be tested in the future decades in order to manage the meteor bodies that are heading our way.
Financial resources
All of these hypotheses are being developed, preparations are being made, and planning is being carried out in order to know on Mars that it will cost a lot of money to make it a reality.
Let us consider a modest example: the distance between Mumbai and New York is 12,500 km, and the average aircraft ticket price is $629. Hence it costs $629 for 12,500 km, so the travel to Mars is 365.85 million km long and returns 365.85 million km long. Now add, calculate, and report back in the comments section.
NASA is now the space agency leading the world's space race in terms of money. The voyage to Mars, on the other hand, is so costly that even NASA cannot finance it. So, how much will it cost to send humans to Mars by 2030, around $1 trillion? The truth is that the United States government cannot afford to spend so much money on NASA. NASA's budget for the fiscal year 2022 is $24.8 billion.
Only 10% of this amount may be put in a Mars mission, while the amount provided to NASA each year only grows by 2%. With this 2% rise, reaching Mars in the next 100 years will be difficult. NASA will have to come up with a novel solution for this.
Conclusion
So, here is a list of the top ten reasons why there are still no humans on Mars. Unless all nations consider a joint Mars expedition, traveling to Mars will remain a pipe dream for us, for which we will need to undertake more effort today. That's all there is to it, my friends.
